Hi Baptiste,
Working on a big latex project, I find the TODO bundle very useful for custom notes. Now I would like to add a TODO item which scans the project for the regular expression /\ref{}/ , that is an empty reference, and list them together with a few words of the paragraph they belong to. I just don't understand regular expressions well enough to do that!
Something like
/\ref{\s*}/
in the Pattern section of the preferences ought to be enough. The double backslash gives a "real" backslash (it's usually used to escape other characters, such as the "\s*" to denote any amount of space between the braces above, or conversely, again as above, to indicate a *literal* brace). Having the "\s*" inside the braces means that if you accidentally leave blank space inside it'll still be flagged.
Cheers, Paul
